To It LU/I/O'Hb it may concern:

Be it known that I, JOHN HAsLaM, a subject of the King of Great Britain and Ireland, and a resident of Athene, ill) Burton street, Darlinghurst, in the State of New South Wales, Commonwealth of Australia, have invented a certain new and useful Improvement in the Construction of Skylights, of which the following is a specification.

111 ordinary skylights when the glazing has to be replaced considerable ditliculty is experienced in removing the old broken glass and putting in a new pane or sheet. The (littlculties are due to the inherent defects in the construction of the sash-bar and the mode of fixing the glazing thereon. consists, essentially, in the adoption of a modified form of sash-bar and of improved means for fixing the pane of glass on the same.

The new sash-bar approximates to the form of a railway-rail having a rectilinear flanged head with sharp arrises and a wide base. The edges of the panes are supported on the ilanges of the base and are maintained in position by a longitudinal cap which envelops the head of the bar, presses down upon the panes, and is sutliciently resilient to maintain them in position. In some positions it will be advantageous to slide the cap endwise on and oil' the sash-bar; but in other positions, owing to want of space. this would be impracticable, and therefore the cap has an articulated hinge at the top, so as to open outward in order that it may be released from the bar. When the cap is in position, it is there maintained by a plate hinged to open in two folds secured to the under side 01 the base of the sash-bar, its hinges permitting it to be turned over the top of the cap, where it maybe secured by a screw or in any other appropriate manner; but in order that the invention may be properly understood reference is made to the accompanying sheet of drawings, in which- Figure l is a side elevation of the end of a sash-bar complete and the glazing lined in position. Fig. 2 is an end elevation of the same, specially showing the hinge to open in two folds. Fig. 3 is a vertical cross-section of the sash-bar and cap shown in Fig. 1. Fig. 4 is similar to Fig. 1, but the cap is articulated or hinged at the top. Fig. 5 is an end elevation of the same. Fig. 6 is an isometrical projection of the hinged cap. Fig. 7 shows the same cap opened outward.

This invention A is the sash-bar, which has a rectilinear flanged head (L with sharp arrises u" and a wide base I), the upper sides ol the llanges of the same being channeled at c c to convey away moisture and at (Z d to receive a pack ing insertion of any suitable kind. The flanged sides of the base 7) are overlaid with the glazing or panes ol' glass 6 c, which will rest upon the insertion in the channels (I (I. The capf is adapted to be slid onto the bar A over one or other ol its ends, when its resilient flanges f will rest upon the upper surface of the glass e and maintain the same lirmly in position. hen it is impracticable to slide the cap oil the cnd ol the sash-bar, the modified form of cap shown in Figs. -l, 5, 6, and 7 is employed. The hinge or articulation g of the cap y" is simple and inexpensive in construction. The top of onc-halt ot the cap is rolled up in a circular form to constitute a socket to receive a spiral which is rolled up on the top ol the other hall of the cap. The spiral part is then inserted or slid into the circular part, and a hinge or articulation is the result. This is shown clearly in Figs. 6 and 7. The end plate ii is in three parts. One part 71 is secured by a screw or screws below the base 1) ol the sash-bar A. This part is articulated at 71 to a plate H, which is adapted to cover the whole ol the end of the sash-bar A and the cap f. This part is in turn articulated at If to the part It", intended to overlie the top of the sash-bar A and the cap f, and when in the position shown in Figs. 1 and at it will be secured by a screw hen it is desired to remove a broken pane, the top 71 is unscrewed and turned over to the position shown by dotted lines in Fig. 4. The cap j'is then slid oil or opened out. the broken pane e is removed, and the new pane put in. The capfis then replaced and the end plate turned over and secured by the screw j, as belorc, and the operation is complete.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent is- 1. A sash-bar consisting ol' a flanged head at the superior end of the web of the bar, a wide base to the sash-bar, a cap adapted to lit over the contour of the superior part of the sash-bar and a closing-platc at the end oi the bar, the same being adapted to prevent the cap from slipping or sliding oil the bar.

2. A skylight-bar consisting of a web with a rectilinear llanged head at the top having sharp arrises and a wide flange at the bottom and resilient 'caps to fit accurately the top of web with channels on each side adapted to l flange of the bar to open or slide and a hinge 15 support the edges of the sheets of glass on to open in two folds secured to thewideflange' each side of the web and an articulated resiliat the bottom end of the bar and capable of ent cap adapted to fit accurately the top being fastened with a set-screw on top flange flange of the bar and to slide and open for the to secure cap and prevent the caps or glass purpose of removal as specified. from sliding ofl the bar. 20 3. A skylight-bar consisting of a web with In witness whereof I have hereunto set a rectilinear flanged head at the top having my hand in presence of two witnesses.
